Huh?

Gusts to 70 mph expected. Weather guy said that snow on roof will
lessen chances of shingles (asphalt, in my case) being lifted. Any
truth to this statement?

Why is snow a good insulator?

Fresh, undisturbed snow is composed of a high percentage of air trapped
among the lattice structure of the accumulated snow crystals. Since the air
can barely move, heat transfer is greatly reduced. Fresh, uncompacted snow
typically is 90-95 percent trapped air.

This is outrageous.

We at People for the Ethical Treatment of Air think that the air
should be set free.
